I'm after getting a Flashed Xbox 360 but had a few questions needed answering first. Modded ISO Games like GTA 4, Left for Dead, CoD WAW and CoD 4 MW will I be able to Host Lobbies with these?
Not sure mate, look in the marketplace for an Xbox or have yours done, modded ISO are around £5 free P&P PistolPete has them all.
Cod4 if you have friends with a jtag you can be infected otherwise there are a lot of games that are ISO modded and can be used in multiplayer even Forza and lfd2 are hot in the scene atm, also its up to you to buy games but you could learn to make your own its cheaper.
